Abstract

Dispositif à percussion (10) comprenant un adaptateur (12) pour queue d'outil, un carter de machine (14) abritant un piston de frappe (16) qui est conçu pour effectuer un mouvement de va-et-vient (A) provoqué par la pression d'un fluide hydraulique, et pour venir frapper ledit adaptateur (12) pour queue d'outil quand le dispositif à percussion (10) est en utilisation. Un élément élastique (18) est disposé radialement saillant à l'extérieur dudit piston de frappe (16) et permet d'amortir le recul (B) dudit adaptateur (12) pour queue d'outil. Le carter de machine (14) présente une surface interne (14i) qui est en regard du piston de frappe (16). L'élément élastique (18) présente une surface interne (18i) qui est en regard dudit piston de frappe (16) et une surface externe (18y) qui est en regard de ladite surface interne (14i) du carter de machine (14). Au moins une partie de la surface externe (18y) dudit élément élastique (18) est directement en regard de la surface interne (14i) dudit carter de machine (14).
